Subject: RE: [R] question on formula and terms.formula()
Thank you so much for your suggestion, Bill.
The R program I try to modify needs match.call() for something else. But the
problem does seem to be caused by this statement as you suggested. Following
this clue, I find out
for terms.formula(mf$formula).

Does your code work if you omit the match.call
Points taken and terms(formula) is used now. Thanks.
